Abstract: A vapor permeable article includes a porous backing substrate and an open fabric applied to one surface of the backing substrate. The open fabric has a greater porosity than that of the backing substrate. The open fabric may be a woven fabric comprising warp (MD) yarns and weft (CD) yarns, and the warp yarns may be of a lower denier than the weft yarns, so as to facilitate hand-tear of the assembled article. The open fabric is coated with an adhesive in such a manner that the open fabric remains porous and vapor permeable. The backing substrate can be a woven, knit or non-woven fabric, or a porous film, such as an apertured plastic film.

Abstract: A vapor permeable article includes a porous backing substrate and an open fabric applied to one surface of the backing substrate. The open fabric has a greater porosity than that of the backing substrate. The open fabric is coated with an adhesive in such a manner that the open fabric remains porous and vapor permeable. The coated article can have a greater tensile strength in the cross direction than in the machine direction, and the adhesive can penetrate into at least a portion of a thickness of the porous backing.
